To read binary format in file, for example here date, which was declare with PIC 9(9) binary, first we need to open the file. Below is the example of value in the file:
Type “hex on” in the command line to view the data in hex format. Since the date is declared as PIC 9(9), length used in the file is (9+1)/2 = 4. Tips: To view the column number, just type “cols”, and to remove the column number, type “res”. In example above, date 20100126 is now happen to be 0132B41E in hex format. Tips: To read hex value, start from left to right, read from up to bottom, and then next column, up to bottom until the end of data length.
If you know the data position but in hex format, how do you convert it into numeric/decimal format? The easiest way is to use this calculator in the internet:
